From my. data, you can see that several of my subjects got the same hours of sleep, but did not work out the same amount of hours. There are many lurking variables in this of survey; for example, age, weight, energy level, stress, and motivation. After looking over my scatterpolot and my data, I have concluded that there is not a strong relationship between my two variables.

What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
